Wooo Hooo. So when I was in the hospital for two weeks in February of this year my GI doctor and I were discussing some different things and thought we would try something out. When I had surgery when I was 15 I had the part of my small intestine taken out that absorbs vitamin B12 from food. I could have eaten a pound of B12 and it would have done me no good.

B12 is a pretty important vitamin. Without it the symptoms are: Common early symptoms are tiredness or a decreased mental work capacity, decreased concentration and decreased memory, irritability and depression.
Sleep disturbances may occur, because B12 may be involved in the regulation of the sleep wake cycle by the pineal gland (through melatonin)[1].
Neurological signs of B12 deficiency, which can occur without anemia, include sensory disturbances due to damage to peripheral nerves caused by demyelination and irreversible nerve cell death. Symptoms include numbness, tingling of the extremities, disturbed coordination and, if not treated in time, an ataxic gait, a syndrome known as subacute combined degeneration of spinal cord.
B12 deficiency can also cause symptoms of mania and psychosis.[2][3]
Recent studies have devalued a possible connection between B12 deficiency and Alzheimer's dementia, and such a correlation is unlikely as of June 2007.[4]
Studies showing a relationship between clinical depression levels and deficient B12 blood levels in elderly people are documented in the clinical literature.[5] and 2002 [6]
Bipolar disorder appears to genetically co-segregate with the hereditary B12-deficiency disorder pernicious anemia [7][8]. (taken from www.wikipedia.org)
To deal with this deficiency I had been giving myself injections, into the muscle in my leg, arm or buttocks once every 3 or 4 weeks. I have been doing that for 20, yes twenty, years! Hmm, that is...only like at least 240 injections extra for me compared to anyone else!

So my doctor and I were just chit chatting and he said, "I don't know why you
have to do the B12 injections, maybe you should try taking a sublingual supplement. Let's have you do that for 2 or 3 months and then see what your levels are at."
Well ladies and gentlemen, I went to the lab early before work and the results yesterday show completely normal levels of B12 in my blood. Wooo Hooo.
No more needles, no more pokes, no more b12 in my glutes!
